SPECIFICATION forming part of Letters Patent No. 640,239, dated January2, 19.00.

Application filed April 17, 1899. Serial No. 713,283. (No model.)

To (tZZ whom it may concern:

Be it known that I, CHARLES TANNER, a citizen of the United States,residing at Cheneyville, in the parish of Rapides and State ofLouisiana, have invented new and useful Improvements in Cultivators, ofwhich the following is a specification.

My object is to construct a cultivator suitable for use in preparingsoil for planting and in cultivating the growing crops; and in theconstruct-ion of such a cultivator my object is to provide means ofreadily regulating the depth, distance apart, and angle of thecultivating-disks, as required to suit the needs of the soil and crop,and also to provide means for adjusting the means between thetractionwheels by the driver easily and quickly.

Myinvention consists of the features herein shown, described, andclaimed.

Figure 1 is a top plan view of the cultivatorconstructed in accordancewith the principles of my invention. Fig. 2 is across-section takenapproximately on the line 2 2 of Fig. 1 and looking in the directionindicated by the arrow. Fig. 3 is an enlarged detail, partlyin section,showing the means of clamping the tongue to the arch-bars. Fig. 4 is atop plan view of one of the end wheels whereby the frame is raised andlowered, the connecting parts being broken away to economize space. Fig.5 is a side elevation showing disk, working tools, and the connectingparts. Fig. 6 is a view analogous to Fig. 5, showing harrow-teethsubstituted for the disk.

The arch-bar consists of the two cross-bars 1 and 1,-placed side byside, the cross-bar 1 having gear-teeth 1" in the lower edge of its freeend; the posts 2 and 2, extending downwardly from the cross-bars l and1, respectively; thehorizontal arms 3 and 3", extending outwardly fromthe centers of the posts 2 and 2 ,respectively; the horizontal arms 4and r, extending outwardly from the lower ends of the posts 2 and 2,respectively, in alinement with the arms and 3, respectively; the bars 5in the outer ends of the arms 3 3 44; the keepers 46 and -16, extendinglaterally from the upper ends of the posts 2 and 2, respectively; thepin it, inserted through the openings 4a in the cross-bars 1 and l, andthe bearing 1, extending downwardly from the vertically from the bars 5,the lower ends of said standards being turned outwardly to form axlesfor the wheel 12. The tongue 7 rests upon the center of the arch-bar andis secured to the arch-bar by means of the clamp 8. The clamp 8 is aflexible strap or bar of iron having its rear end attached to the underside of the tongue 7 by means of the bolts 8 said strap passingforwardly under the arch-bar and then upwardly through the opening 8 inthe tongue 7 and having an eye 8 at its upper end above the tongue. Thepost 48 extends upwardly from the tongue 7, and the lever 47 ispivotally connected to the upper end of said post and to the eye 8. Thehandle end of the lever 47 carries the spring-dog 49 in engagement withthe rack-bar 50, which extends upwardly from the tongue back of the post48. The seat 9 is secured to the rear end of the tongue 7. The cross-bar1 slides through the keepereifi, and the cross-bar 1 slides through thekeeper-4L6. Ashaft 43 is mounted in the bearing 1. A'crank 43 isattached to the rear end of said shaft for operating the same, and apinion 43 is fixed upon the forward end of said shaft in engagement withthe teeth 1 WVhen the pin 44 is removed, the operation of the crank 43slides the cross-bars 1 and 1 relative to each other, thus movingthewheels 12 to or from each other, and when said wheels have been adjustedto the desired distance the pin 4P is replaced, thus holding the wheelsrigidly connected together.

The cross-bar 38 is rigidly secured to the tongue 7 some distance infront of the archbar, and the supporting-arms 10 extend backwardly fromthe ends of the crossbar 38 over the arclrbar to points beyond the seat9. Said arms 10 rest upon the arch-bar. The levers 13 are rigidlysecured to the upper ends of the sliding standards 6 and extendhorizontally backward, the rear ends of said levers being connected bythe connecting-rods 14, which are located in front of the seat 9 inposition to be manipulated by the driver for the purpose of guiding thewheels 12. .The levers 15 are pivotally connected between the lugs 16upon the upper ends of the sliding standards 6. The chains 17 connectthe rear ends of the levers 15 with the spools 18, said spools beingmounted upon the shafts 19 of crossbar 1. The sliding standards 6operate 1 the hand-wheels 11, said shafts being carried by bearings atthe rear ends of the arms 10. The chains are wound upon the spools 18 bymanipulating the hand-wheels 11, and the pawl-and-ratchet mechanisms 36hold the spools from unwinding. \Vhen the driver ma nipulates thehand-wheels 11 to Wind or unwind the chains upon the spools 18, thearchbar and the connecting parts are raised or lowered upon the slidingstandards 6. The connecting-rods 20 are pivotally attached to the tongue7 a considerable distancein front of the cross-bar 38, and pin-openings21 are formed in the outer ends of said connectingrods. Theyoke-clevises 22 are slidingly mounted upon the outer ends oftheconnecting-rods 20 and are held adjustably in position by means ofthe pins 22, inserted downwardly through the yoke clevises 22 andthrough the openings 21 in the connectingrods. The yoke -clevises 22 areslidingly mounted upon the arms l and 4, there being pin-openings 21through said arms and similar openings through the clevises 22" toreceive the pins 22, as required to adjust the clevises in and out uponthe arms 4 and 4*. The shafts 23 have a series of openings 24 andflattened ends 25, and said shafts connect the clevises 22 and 22 andform support-s for the working tools 33.

Bearing-blocks 27 and 27" are slidingly mounted upon the shafts 23. Theset-collar 30 is mounted upon the shaft 23 behind the bearing-block 27and held adjustably in position by means of the pin 31,inserteddownwardly through the collar into the openings 24. The set-collar 35 isadjustably mounted upon the shaft 23 in front of the bearing-block 27and is held adjustably in position by means of the pin 31, inserteddownwardly through the collar into the openings 24. bearing-blocks 27and 27 are connected by the arm 27, extending downwardly from onebearing-block and then upwardly to the other bearing-block. Thesegmental arms 28 extend upwardly from the bearings 27, and the arms 32extend upwardly from the set-collar 30. There are openings in the upperends of the arms 32 to receive the pins 31, and there is aseries ofopenings in the segment 28 to receive the pin 31, as required to adjustthe arm 27 relative to the vertical line. The plate 26 is placed in ahorizontal position against the bottom of the arm 27, and a similarplate 26 is placed below the plate 26. The bolt 34 is inserted upwardlythrough the plate 26 4 through the plate 26, and through the arm 27.

There is a series of openings 24 formed in the' disk 26 and'one or moreregistering openings in the disk 26", and the pin 31" is inserteddownwardly through said openings, as required to-adjust one diskrelative to the other. The arms 33 are attached to the disk 26 andextend downwardly, and the disk cutters 33 are attached to the arms 33,as shown in Fig. 5. In Fig. 6 a plate 33 is attached to the disk 26% andthe harrow-teeth 33 are attached to the plate 33". The harrow-teeth andthe The disk cutters are interchangeable, and I call them both workingtools. The doubletree 39 is attached to the tongue 7 a short distance infront of the cross-bar 38 by means of the pin 39, and braces 29 run fromthe pin 39 to the forward ends of the arms 10. The chains 41 run fromeach end of the doubletree 39 to the singletree 41, and the chains 42run from the singletree to the clevises 22. The staychains 37 connectthe outer ends of the crossbar 38 with the shafts 23. The braces 29extend from the forward ends of the arms 10 or from the cross-bar 38rearwardly and connect to the pins 45, projecting inwardly from thelower ends of the posts 2 and 2.

The adjustment of the working tools back and forth upon the shafts23counterbalances the weight of the driver upon the seat 9. The operationof the hand-wheels 11 raises and lowers the arch-bar and connectingparts. The operation of the crank 43 adjusts the wheels 12 to and fromeach other. The adjustment of the clevises 22 and 22 moves the workingtools to and from each other. The adjustment of the disk 26 relative tothe disks 23 changes the direction of the axis of the disks 33 relativeto the line of travel and the adjustment of the arms 32 relative to thesegment 28 by means of the pin 31 changes the axis of the disks 33relative to a horizontal line.

The lateral adjustment of the framework permits of its being used totake out the middles' of rows, thereby enabling the operator tocultivate the crops and take out the middles with the same implement.

The line of draft being directly from the end of the shafts to which theworking tools are secured gives the animals a direct pull without sidedraft.

It is obvious that changes in the exact construction may be made withoutin any Way departing from the distinguishing features of my invention.
